Power/Performance Bits: July 27
By Jesse Allen - 27 Jul, 2021 - Comments: 0

Amplifying light for lidar Engineers at University of Texas at Austin and University of Virginia developed a light detector that can amplify weak light signals and reduce noise to improve the accuracy of lidar. "Autonomous vehicles send out laser signals that bounce off objects to tell you how far away you are. Not much light comes back, so if your detector is putting out more noise than th... » read more

The Great Quantum Computing Race
By Mark LaPedus - 26 Jul, 2021 - Comments: 0

Quantum computing is heating up, as a growing number of entities race to benchmark, stabilize, and ultimately commercialize this technology. As of July 2021, a group from China appears to have taken the lead in terms of raw performance, but Google, IBM, Intel and other quantum computer developers aren’t far behind. All of that could change overnight, though. At this point, it's too early t... » read more
